Abstract
A balancer arrangement for a two cylinder in-line internal combustion engine that includes a drive gear formed on the crankshaft between a pair of throws and between a pair of bearing surfaces. A pair of balance shafts are driven from this drive gear and have inertial masses coupled to them through a torsional vibration damper. The inertial masses are disposed between the adjacent pair of cylinders and within the crankcase so as to provide a compact engine.
